After seeing the official press renders of the LG Marquee — the Optimus Black, really — we knew that an official Sprint announcement was on its way. The carrier has made the phone official with an availability date of October 2.

The LG Marquee runs Android 2.3 Gingerbread and packs a 1GHz single-core processor. It has a super-bright four-inch WVGA IPS NOVA display, 512MB RAM, 2GB ROM, five-megapixel autofocus camera and with flash and two-megapixel front-facing webcam, powered by a 1500 mAh battery. It will be available for a pre-sale between September 20-27 online for $99.99 and will land on October 2 for the same price with eligible upgrade or a new two-year contract and after a $50 mail-in rebate via reward card.
